em viết cái CODE để xử lý ngắt mà sao nó cứ báo lỗi chỗ enable_interrups (INT_LED)
Mong các sư phụ giúp đỡ
#include "D:\pic-c\a\bai2.h"
#use delay (clock=2000000)
//#device PIC16F877A *=16
int8 mode,i;
byte temp;
#INT_EXT
EXT_LED()
{
mode++;
if (mode==3) mode=0;
}
void program1();
void program2();
void main()
{

setup_adc_ports(NO_ANALOGS);
setup_adc(ADC_OFF);
setup_psp(PSP_DISABLED);
setup_spi(SPI_SS_DISABLED);
setup_timer_0(RTCC_INTERNAL|RTCC_DIV_1);
setup_timer_1(T1_DISABLED);
setup_timer_2(T2_DISABLED,0,1);
setup_comparator(NC_NC_NC_NC);
setup_vref(FALSE);

enable_interrups(INT_LED) ;
ext_int_edge(H_TO_L);
enable_interrups(GLOBAL) ;
mode=0;
while(1)
{
// TODO: USER CODE!!
output_b(0x00);
delay_ms(500);
switch (mode)
{
case 0rogram1();break;
case 1rogram2();break;
}

}
}
void program1()
{
set_tris_b (0x00);
output_b(0xf0);delay_ms(300);
output_b(0xff);delay_ms(100);
}
void program2()
{
temp=0xff;
for (i=0;i<=8;i++)
{ output_b(temp);
delay_ms(150);
temp <<=1;
}
}
